Sweet, Sour, Salty and...Fat? Scientists Add a New Basic Taste
The thousands of taste buds on a human tongue each contain as many as 100 taste receptors. The interaction between those receptors and the chemicals in our food determine the taste of that hamburger or salad you’re having for lunch.
Our sense of taste has long been broken into four basic categories — sour, sweet, salty and bitter. A fifth basic taste was added more recently: umami, which means “delicious” in Japanese but refers to a meaty or savory flavor sensation. Now researchers claim there’s a sixth basic taste.
Scientists at Purdue University have published a new study in the journal Chemical Sense that they say provides evidence that chemicals called nonesterified fatty acids (NEFA) — in other words, fat — causes a taste sensation that is different from the other five tastes. The researchers have proposed that the new taste be referred to as “oleogustus.” “Oleo” is the root word for oily or fatty in Latin and “gustus” means taste.

The researchers emphasize that they are talking about a taste, not just the creamy mouth feel you get from eating a rich piece of meat or a dish loaded in butter.
The fat that delivers that creamy, smooth feeling is a triglyceride, made up of three different fatty acids, they explain. Oleogustus — a gag-inducing taste on its own, but much more appetizing in combination with other flavors — comes from only one of those fatty acids that breaks off from the larger molecule in the food or as you’re chewing.
This finding has the potential to generate big changes in the food industry. Understanding the taste component of fat can do more than add to our knowledge of how our brain and digestive system interact. It may also help the food industry create more appealing, and potentially healthier, products.

The High Cost of Child Poverty
Childhood poverty cost $1.03 trillion in 2015, including the loss of economic productivity, increased spending on health care and increased crime rates, according to a recent study in the journal Social Work Research. That annual cost represents about 5.4 percent of U.S. GDP. “It is estimated that for every dollar spent on reducing childhood poverty, the country would save at least $7 with respect to the economic costs of poverty,” says Mark R. Rank, a co-author of the study and professor of social welfare at Washington University in St. Louis. (Futurity)
Do You Know What Your Tax Rate Is?
Complaining about taxes is a favorite American pastime, and the grumbling might reach its annual peak right about now, as tax day approaches. But new research from Michigan State University highlighted by the Money magazine website finds that Americans — or at least Michiganders — dramatically overstate their average tax rate.
In a survey of 978 adults in the Wolverine State, almost 220 people said they didn’t know what percentage of their income went to federal taxes. Of the people who did provide an answer, almost 85 percent overstated their actual rate, sometimes by a large margin. On average, those taxpayers said they pay 25.5 percent of their income in federal taxes. But the study’s authors estimated that their actual average tax rate was just under 14 percent.
The large number of people who didn’t want to venture a guess as to their tax rate and the even larger number who were wildly off both suggest to the researchers “that a very substantial portion of the population is uninformed or misinformed about average federal income-tax rates.”
Why don’t we know what we’re paying?
Part of the answer may be that our tax system is complicated and many of us rely on professionals or specialized software to prepare our filings. Money’s Ian Salisbury notes that taxpayers in the survey who relied on that kind of help tended to be further off in their estimates, after controlling for other factors.
Also, many people likely don’t understand the different types of taxes they pay. While the survey asked specifically about federal taxes, the tax rates people provided more closely matched their total tax rate, including federal, state, local and payroll taxes.
But our politics likely play a role here as well. People who believe that taxes on households like theirs should be lower and those who believe tax dollars are spent ineffectively tended to overstate their tax rates more.
“Since the time of Ronald Reagan, American[s] have been inundated with messages about how high taxes are,” one of the study’s authors told Salisbury. “The notion they are too high has become deeply ingrained.”
Wealthy Investors Are Worried About Washington, and the Debt
A new survey by the Spectrem Group, a market research firm, finds that almost 80 percent of investors with net worth between $100,000 and $25 million (not including their home) say that the U.S. political environment is their biggest concern, followed by government gridlock (76 percent) and the national debt (75 percent).
Trump’s Push to Reverse Parts of $1.3 Trillion Spending Bill May Be DOA
At least two key Republican senators are unlikely to support an effort to roll back parts of the $1.3. trillion spending bill passed by Congress last month, The Washington Post’s Mike DeBonis reported Monday evening. While aides to President Trump are working with House Majority Leader Kevin McCarthy (R-CA) on a package of spending cuts, Sens. Susan Collins (R-ME) and Lisa Murkowski (R-AK) expressed opposition to the idea, meaning a rescission bill might not be able to get a simple majority vote in the Senate. And Roll Call reports that other Republican senators have expressed significant skepticism, too. “It’s going nowhere,” Sen. Lindsey Graham said.
Goldman Sees Profit in the Tax Cuts
David Kostin, chief U.S. equity strategist at Goldman Sachs, said in a note to clients Friday cited by CNBC that companies in the S&P 500 can expect to see a boost in return on equity (ROE) thanks to the tax cuts. Return on equity should hit the highest level since 2007, Kostin said, providing a strong tailwind for stock prices even as uncertainty grows about possible conflicts over trade.
Return on equity, defined as the amount of net income returned as a percentage of shareholders’ equity, rose to 16.3 percent in 2016, and Kostin is forecasting an increase to 17.6 percent in 2018. "The reduction in the corporate tax rate alone will boost ROE by roughly 70 [basis points], outweighing margin pressures from rising labor, commodity, and borrow costs," Kostin wrote.
